Fire-fighting hoses - Rubber and plastics suction hoses and hose assemblies

This document establishes the requirements and test methods for rubber and plastics suction hoses for fire-fighting purposes. These hoses can also be used manually to supply unpressurized water to the pump or for water discharge.NOTE       All pressures are expressed in megapascals and in bar (1 MPa = 10 bar).Additional requirements are specified for hose assemblies, that is, hoses with couplings already fitted, where this is carried out by the hose manufacturer (see Clause 8).Type A (rubber) hoses are intended for use at a minimum temperature of −20 °C and Type B (thermoplastics) hoses are intended for use at a minimum temperature of −10 °C.

Fire-fighting hoses - Rubber and plastics suction hoses and hose assemblies

This document establishes the requirements and test methods for rubber and plastics suction hoses for fire-fighting purposes. These hoses can also be used manually to supply unpressurized water to the pump or for water discharge.

NOTE       All pressures are expressed in megapascals and in bar (1 MPa = 10 bar).

Additional requirements are specified for hose assemblies, that is, hoses with couplings already fitted, where this is carried out by the hose manufacturer (see Clause 8).

Type A (rubber) hoses are intended for use at a minimum temperature of −20 °C and Type B (thermoplastics) hoses are intended for use at a minimum temperature of −10 °C.

Fire-fighting hoses - Rubber and plastics suction hoses and hose assemblies

L'ISO 14557:2002 présente les exigences et méthodes d'essai applicables aux tuyaux d'aspiration en caoutchouc et en plastique destinés à la lutte contre l'incendie. Des exigences supplémentaires sont spécifiées pour les flexibles, c'est-à-dire des tuyaux avec des raccords déjà montés, lorsque le montage est effectué par le fabricant de tuyaux. Les tuyaux de type A (en caoutchouc) sont conçus pour une utilisation à une température minimale de - 20 °C tandis que les tuyaux de type B (thermoplastiques) sont conçus pour une utilisation à une température minimale de - 10 °C.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
